Added complete call-seq documentation for all Method extension methods in
mrblib/method.rb (3 methods):
## Method Extension Methods:
- to_proc: converts Method object to Proc for functional programming
patterns, enables use with &: syntax for concise method references
and supports full argument passing including blocks and keyword arguments
- << (left composition): method composition operator that calls other_proc
first then this method, enables right-to-left function composition with
mathematical notation f(g(x)) for building complex transformations
- >> (right composition): method composition operator that calls this method
first then other_proc, enables left-to-right function composition with
pipeline notation for intuitive data flow transformations
